Decode On Copy od Brian McDonald

Decode On Copy tries to base64 decode any text that you copy, and if it can be decoded to a valid URL, the URL will be copied to your clipboard instead. It is best demonstrated by example.

• The simplest case is where you copy something that is not an encoded URL, like http://www.example.com. Since the text you copied can't be decoded to a valid URL, you will end up with http://www.example.com on your clipboard.
• Now, if you copy aHR0cDovL3d3dy5leGFtcGxlLmNvbQ==, Decode On Copy will notice that it can be base64 decoded to http://www.example.com and will copy http://www.example.com to your clipboard instead of aHR0cDovL3d3dy5leGFtcGxlLmNvbQ==.
• Decode On Copy can also detect URLs that have been base64 encoded multiple times. So copying YUhSMGNEb3ZMM2QzZHk1bGVHRnRjR3hsTG1OdmJRPT0= would also result in http://www.example.com being copied to your clipboard.
